THOMAS COLLIER, OF TREZEVANT, TENNESSEE.

BALING-PRESS.

SPECIFICATION forming part'of Letters Patent No. 723,652, dated March24, 1903. Y

Application filed SeptemberlO, 1902. Serial No. 122,832. (No modelfl Tocaf/ZZ- wwm it may concern;

Beit known that I, THOMAS COLLIER, a citizen of the United States,residing at Trezevant, in the county of Carroll and State of Tennessee,have invented new and useful lmprovements'in Ealing-Presses, of whichthe following is a'specibfication. l

This invention relates to baling presses, and particularly to the Vtypeknown as a rebounding plunger. A

The object of the invention is to provide a durable and efficient meansfor applying force to the plunger and to compress the bale within thebaling-chamber.

Another object is to provide a novel construction of retracting devicefor causing the plunger to rebound into position to be again projectedtoward the bale as soon as the baling-lever is released therefrom.

l/Vith these objects in view the invention consists in certain novelfeatures of construction and combination of parts to be referred tohereinafter and illustrated in the accompanying drawings, in which'-Figure v1 is a' perspective view of a balingpress constructed inaccordancewith my invention. Fig. 2 is -a top plan view of the same.Fig. 3'is a vertical longitudinal sectional view'through the same. Fig.4' is a transverse sectional View on the line 4 4 ofl Fig. 3, and Fig. 5is a cross-sectional view on the line 5 5 of Fig. 3. ,Y I

The reference-numeral 1 designates a balin g-chamber which is providedwith sides, top, and bottom. At the rear end of the balingchamber andsecured to the transverse basebar 2 are two upwardly-projecting rods 3and 4, which project through a transverse bar 5, which is securedthereto by nuts 6 and 7. 'Intermediate the ends of the bar 5 is an eyeor socket 8, through which projects the reduced end 9 of the lever 10,which is fulcrumed to the eye or socketV and is fastened to the top ofthebaling-chamber bya pin 11, which projects from a rib or bar 12 on thetop thereof. The top of the baling-chamber is secured to tworearwardly-extendin g spring-arms 13 and 14, which are interposedbetween the rods 3 and 4. By pressing down upon the lever 10 thespring-arms will be forced toward the bot tom of the baling-chamber,carrying with them the top, which will clamp the headblock 15 to anypoint of adjustment from the rear of the chamber to a point adjacent thehopper.

The arms and top can be held in their ad justcd position-by means of abail 16, which is pivoted to thev top of the baling-chamber and engagesone of the teeth of the rack 17 on the lever 10. The head-block 15isprovided With'dovetail grooves 18, extending transversely thereof, sothat thebaling wire or tie can be passed in the grooves when the bale ismade so as to tie up the bale.

Projecting forwardly from the baling-chamber are two parallel guides 19and 20, Which are formed integral with the arms 13 and 14 and serve assides for the hopper 21 and as guides for the plunger, to be referred tohereinafter. The sides are secu red to the bottom and top by a clamp 22,which comprises two transverse bars at the top andV bottom,`con nectedby adjusting-rods at theirends. The revoluble roller 23 is arranged insuitable journals in the top edges of the sides, so as to assist thematerial to be baled in entering the hopper. are arranged parallel slots24, in which are spring-fingers 25, so as to retard the backwardmovement of the material to be baled when it is compressed by theplunger.

As above stated, the plunger is guided by the sides 19 and 20 and isassisted vby a top guide 26. This plunger, which is designated by thereference-numeral 27, has a rearwardly-extending iiange 28 at its topwhich may bear against the guide 26 and prevent an upward displacementthereof. From the bottom of the follower 27 is a forwardly-extendingfollower-bar 29, whichis braced to the follower by a suitable metallicbrace 30. This follower-bar 29 is provided with alongitudinally-arranged series of transverse teeth 31, which are adaptedto be engaged successively by a projecting lip 32 of the plungerleverThis plunger-lever is pivoted to a pair of swinging link-bars 34 and 35,which are in turn pivoted to the sides 19 and'20. A pivot or bolt 36,which connects the'plungerlever to the links, constitutes a fulcrum forthe lever, so that the lever can 'be raised out of engagement with therack after the plunger is projected forward, so as to engage the teethsuccessively. When the follower has On the sides'of the hopper IOOreached the end of its stroke or has been projected as far as the leveris capable of projecting it, a shoulder 37 on the under side of thefollower-bar will be engaged by a pivoted trip-lever 38, whichconstitutes a locking means whereby the follower will be held in itsprojected position. On the forward end of the lever 38 and on theopposite side of the fulcrnm 39 is a weight 40, which will cause the endopposite from the weight to be tilted up into engagement with theshoulder 37 as soon as the shoulder has passed the end of the lever.

Inasmuch as the lever normally rests in a slot 4l of the bottom, thefollower-bar can move back and forth thereover without interruptionuntil the shoulder 37 moves rearwardly past the end of the lever.Pivoted to a vertical standard or support 42, carried by one of thesides, is a weighted lever 43, on one end of which is an adjustableweight 44. The forward end of the lever is connected to the follower-barby a link 45. As soon as the lever 33 has reached the end of its strokethe end which has engaged the rack will be forced up to an engagementwith the U-shaped projection or loop 46, interposed between the sides 19and 2O and immediately above the lever. This projection or abutment 46will act as a permanent fulcrum on the lever, so that a downwardpressure of the handle thereof will cause a pin 47 to come in contactwith the lever 3S, thereby depressing it into a slot 4l and releasingthe follower-bar. As the resistance to the retraction of the lever willthen be removed, the weight 44 will be sufficient to carry one end ofthe lever downward, thereby raising the other, during the course ofwhich movement the followerbar will be retracted through the medium ofthe link 45 to a position whereby it can again be operated by a lever33. The rear movement of the follower is limit-ed by two stops 34a and35i, which rest on the bottom of the case and against which the followeris adapted to strike. These stops prevent the follower-bar from strikingagainst the pin and causing it to break off. Antifriction-rollers 48 and49 are connected to a transverse shaft 50 and run in the bottom of thebaling-press.

It will thus be seen that I have provided an effective and durablebaling-press which will readily perform the services for which it isintended. l
